WEATHER-STRIP. 1

igeaasre.

To all whom it may concern:

Be it known that I, HARRY. S. Davis, a citizenof v the United States, residing at Indianapolis, .in the county of Marion and Stateof Indiana, have invented certain new and useful Improvements. in \Veather- Strips, of-which the following isa specifica- 'tion.

Thisinvention relates to weather strips, especially adapted. for windows of a type which includes relatively slidable sashes and in which it'is desirable to provide means to prevent theentrance of dirt, air, or rain, it being among the objects of this invention to devise a weather strip which obviates the use of the ordinary parting strip, holds the sashes in alinement, reduces friction in slidin is simple, eflicient, and easy to install.

In carrying the objects of my invention into effect, I provide longitudinal, beaded members which are-preferably secured to the window frame at the position of the ordinary parting strip. Corresponding, complementary, beaded members are secured to the inner side of the outer sash and to the outer side of the inner sash, respectively, cooperating with the first mentioned beaded members to provide supporting and alining means, and 'a weather strip for the window. I also usually provide weather strips along the inner top edge of the outer sash and the outer bottom edge of the inner sash, these latter strips serving to close the top and bottom openings, and are in perfect alinement with the longitudinal strips, thus efficiently protecting against the entrance of air, etc. In order to prevent excessive strain on the strips I preferably secure them at such a point on the sash where the least expansion and contraction takes place, and the strips are so formed as totake up such strains at several points.

Referring to the accompanying drawings forming a part hereof and in which similar reference characters denote similar parts.

Figure 1, represents a horizontal sectional view of a portion of a window showing the construction of my longitudinal members,

The window 1 has the ordinary casing 2,

and if thewindow is an old one has a, parting bead 3 for the reception of the parting strip which acts as a guide keeping thetwosashes4 and 5 inalinement. Window panes 6- and 7 are'secured in sashes '4 and -5,zre-

spectively.-. I i

Inthis device the parting stripis dispensed with-and a member 8' substituted therefor, said member extending transversely of the vertical trend. of thesashes 4 and: 5: andv terminating at ;its edges in beads which are "circular in cross section, these beads terminating in legs 9 and 10. The beads are sobent that the inner ends of the legs rest against'the outer face of the member 8 and in close proximity to each other, said .legs from their inner to. their outer ends being flared'or gradually spread apart and having their extreme ends extended laterally, thelateral portions being secured to the frame'2 byymeans of nails ll and'12' or other equivalent.

By separating the outer ends of the legs 9 andplO the member 8, is. fully reinforced and braced to withstand any lateral strain directed thereagainst by the sashes 4 and 5,

and when the member is being used in conj j nection with an old frame from which the parting bead has'been removed the legs 9 and 10 completely cover the groove in the frame from which the head has been removed and thus excluding air and dust from passing through the groove. Cooperating members 13 and 14 having off-set portions 15 and 16, respectively, aresecured to the adjacent faces of the window sashes 4 and 5, respectively, by nails, or similar means, 17 and 18, the offsetportions 15 and 16 resting against the faces of the sashes so that no grooves or depressions are required in which a to seat the ofiset portions; The members 13.

and 14 each havev a socket at one edge which closely envelop the beads on the member 8 and serve not only as a means for preventing air entering, but also to take the place of the ordinary parting stripin guiding and alining the sashes. e Along the top of upper sash 4, on the inside thereof, is secured a weather strip 19 by means of nails 20. A corresponding, complementary, the top of the window frame by nails 22. In a similar manner weather strip 23 is secured along the outside of the bottom of the lower sash by nails 24 and cooperating with weather strip 25 secured to the bottom weather strip 21 issecure'd to of the frame by nails 26. These top and bottom weather strips are so fitted that they are in substantially perfect alinement with the ends of the longitudinal strips 13v and 14, I

periphery ofthe window'for air. to enter,

andthe weather strip holds both sashes rigid and in alinement and eliminates friction which ordinarily occursdue to swelling of the parts. The nails 17 and 18 are set at points where expansionand contraction are a minimum, and approximately midway between the edges of thesash. It requires no coring of the sash, nor special tools, nor

a skilled mechanic to apply my Weather strip;

Having thus fully described my said invention, what I claim as new and desire 'to secure by Letters Patent, is: ing longitudinally placed members extend- 1. A weather strip for windows comprisi'ng transversely between the movable parts 'of the window structure the longitudinal edges of said members being formed into beads, legs integral'with said beads and having their inner ends in juxtaposition to each other and their outer ends spread apart, means for securing the outer ends of said legs to the frame portion of the window structure, and coeperating members attached to the faces of the movable members of the window structure, said coeperating members having sockets thereon adapted to closely envelop the beads of saidtrans versely extending members.

2. In .a Weatherstrip construction the combination with a Window structure including a frame and an upper and lower sash, of a member extending longitudinally of the frame andtransversely betweensaid sash,'beads at the longitudinal edges of said member said beads being circular incross section,legs integral with said vbeads and substantially at right angles to said member, said legs flaring outwardly from their inner totheir .outer ends forgbracing and reinforcing said legs, means for attaching saidlegs tolsaicl frame for forming a stationary reinforced' separating strip, and c05perating members attached to theameetingsurfaces of said sash, said cooperating members'having sockets formed thereon for receiving and surrounding said beads.

In witness whereof, I have hereunto set .hand and seal at Indianapolis, Indiana, this 28th day of February A.]D.,nineteen hundred and twenty., i
